when that happens, be patient, and click CTRL-ALT-F1. it might take a
while, but that should throw you to a TTY.
if there's anything drastic, like a major driver fault (i've seen some
intel graphic drivers locking up a computer that way), the kernel would
be spitting endless amounts of errors right on any TTY you go to.
if not, then try to login, and once you're logged in, type the command:
top

this should show the most consuming processes.

hope this helps.
